Copper Production Plant By Heap Leaching

Apr 12, 2021

Sulphide Heap Leach Process. The leached copper in solution is then processed by solvent extraction-electrowinning (SX-EW) to produce LME grade A cathode, which has a copper purity of more than 99.99%. All of the LME grade A copper cathode produced onsite is sold at a premium in liquid global markets whereas for concentrate, sales proceeds are

    A leaching solution of weak sulphuric acid is sprayed over the rock on the pad and allowed to percolate through to the base. As the solution passes through the heap, the copper-bearing mineral dissolves into solution. The copper-bearing solution accumulates in the collection pond and is piped to a nearby SX-EW plant for metal recovery. Leaching

    Jun 22, 2019 Heap leaching is a simple means of recovering copper from oxide and oxide-sulfide ores. Although this method requires relatively low capital investment, it suffers from low copper recoveries and relatively high acid consumption. The objectives of this study were (1) to determine what factors influence these shortcomings, and (2) to establish a

The leaching experiments were performed using sulphuric acid solutions, whereby the kinetics of copper leaching was investigated with respect to acid concentration and solid to liquid ratio. The copper concentration in the leach solution ranged from 0.80 to 1.75 g dm-3. The total Cu recovery rate ranged from 30 to 56 %, whereas the
